Abstract: 762,673. Supply systems for space discharge lamps. GENERAL ELECTRIC CO., Ltd. Oct. 22, 1954 [Oct. 22, 1953], No. 29235/53. Class 38 (4). Third harmonic currents drawn by two or more electric discharge lamps 1, 12 from one phase of a three-phase star connected A.C. supply are reduced by the provision of a harmonic correcting circuit comprising a capacitor 10 and an inductor 11 serially connected directly across the line L and neutral N supply terminals 5, 6 so as to be wholly in parallel with the lamps, the capacitor and inductor being of such value as to be at or near resonance at the third harmonic of the fundamental frequency of the supply whereby to generate a current of third harmonic frequency which is in phase opposition to the third harmonic frequency current drawn by the lamps; this harmonic correcting circuit is related to circuits of the twin lamp type wherein the lamps 1, 12 are respectively capacitively and inductively ballasted, e.g. by capacitors 26, 27 and an inductor 28, and by an inductor 15. As shown, starting is effected by respective earthed starting strips 19, 20 and filament heating transformers 23, 31. In other embodiments two lamps are started instead by glow switches, and each ballast impedance may be common to a number of lamps in series. The harmonic correcting circuit is arranged to resonate at a frequency of between 2.4 and 3.2 the fundamental frequency of the supply by trial and error selection of the values of its components 10, 11 and one such correcting circuit may be common to a number of twin lamp circuits. Suitable values and construction of circuit components are described in the Specification.

Abstract: 699,234. Regulating switches. THORN ELECTRICAL INDUSTRIES, Ltd., STRANGE, J. W., and LOCKYER, J. S. Nov. 3, 1950 [Nov. 17, 1949], No. 29486/49. Class 38 (v) In an arrangement for controlling the brightness of a series of lamps of different colours for stage lighting &c., a master control member causes the simultaneous movement of secondary control members, associated each with a different colour, at rates which may be individually adjusted. Thus, the secondary control members may move simultaneously from a position of zero illumination for each colour to any desired intensity of illumination for each colour. In the form shown the master control member rotates a shaft 75 carrying a series of cam nests 73, one for each unit. Each nest is longitudinally adjustable along the shaft 75 by a handle 77, the adjustment determining which of a series of cam grooves 74 A, B, C, is to be engaged by a pin 72 on a lever 62 and thereby also determining the rate of movement of the arm 62, which is driven by the cam. Each arm 62 carries a contact which sweeps over tapping contacts on a support 59. The Provisional Specification describes also a construction in which a master control member operates simultaneously a number of arms on a shaft, each arm carrying a stud adjustably fixed along its length and engaging a slot in a horizontal yoke which joins two members sliding along vertical guides and engaging series of contact. In a modified form of the above each stud sweeps over a series of parallel contact bars.

[Class 100 (iv)] Type-lever actions; platen-impression arrangements.-Impression is effected noiselessly by causing the platen to advance against the types when the latter are practically stationary, the movement of the platen being in the opposite direction to that of the types. The platenadvancing mechanism may comprise a spring in connection with the universal bar. In the action shown in Fig. 1, the type-lever 9 is formed with a slot 8 engaging a pin 7 on a lever 5 which is connected by a bell-crank 3 to the key-lever 1. The platen-frame 15 is mounted on parallel links 13, 14 on the carriage 12 and is provided with a rod 16 engaging the forked end of a lever 17 which is pivoted at 18 to the framework and is normally held in contact with a stop 20 by means of a spring 19. The lever is connected to a toggle 22, 23, a member 47, mounted on a pivot 25, Fig. 4, on the toggle-link 23, being formed with lugs 27, 28 for engaging lugs 29, 30 on a plate 31 which is carried by links 32, 33 and is connected to a universal bar 21 co-operating with cams on the heels of the typelevers. A leaf spring 41, anchored at the end 42 and arranged between pins 43, 44 on the toggle-link 22 and pins 45, 46 on the member 47, throws the member from side to side when the toggle is moved below or above the horizontal position. On depression of the keylever, the type-lever is swung upwards, the speed increasing and then decreasing, and the pin 7 being finally effective to hold the typelever in printing position. Meanwhile, the lugs 29, 27 co-operate, the toggle 22, 23 is straightened, the lever 17 is rocked slightly, the spring 19 is stretched, and when the toggle moves below the horizontal position, the spring returns the lever and impression is effected. During the over-centre movement of the toggle, the spring 41 rocks the member 47, and the lug 28 is brought into position for co-operating with the lug 30 at the next operation of the keys. The initial position of the platen can be adjusted slightly to adjust the period of impression.
